Help me defeat herc

As i can see your team heavily emphasized on art and stall team.
Some example :
- Archuria ( white ce ), georgios, mashu, Tamamo/Waver, Tamamo Lancer ( white ce ), Chloe ( white ce )
Level your tank just a bit also good job caring for Hans there, but if you really desperate to beat Hercules :
- Single Grailed Chu with MLB white ce.
- Single Nero OG with MLB white ce.
- more mysterious strong solo servant out there.
- ask them first, so they can help and add you !

Alright good luck :)

Squirtoria with MLB white rose princess and Tamamo Caster plus one servant that can tank/taunt. Then you can go and say "So as I pray, Unlimited Squitgun Works".

Squirtoria with white rose and Mash with either def ce or 2030 + MAX Waver. Keep Deon, Tama lancer and Herc in the backline in case the original setup didn't work. Be sure to spam def buffs every time it's open.

I think you should build your team as an Arts Crit team centered on Squirtoria and have the following as supports: Chloe as a secondary damage dealer, Chevalier d'Eon and Mash for their tanking as supports and pick either Herc or Tamamo Lancer as your last stand support. Finally, you can borrow a friend's Waver or Tamamo Caster. As for mystic code, try running the Atlas Mystic Code as it has debuff cleanse as well for your Squirtoria.

Hope this helps!

Yeah you have plenty of options available to you. I think your biggest problem right now is just leveling your servants. The exhibition bosses were intended for max level teams.

I'd say open up with Archertoria, Mash, and a support Waver or Tamamo caster. Keep Archertoria alive for as long as humanly possible. Keep Chloe, Kintoki and Lancer Tamamo on the backline.

Despite what other people are saying, I would encourage you to NOT MLB the wedding CE, but instead put one on Archertoria and the rest your backline servants. You want to stall this fight out for as long as possible while dealing as much damage as possible. If you get an MLB CE, and your main damage dealer falls, you're screwed against Herc. It's not so bad when you have a max level team, but in your case, you could be headed for trouble.
